- Awesome, Dear Boy:
- Josie Maran (Marishka) said as much about playing a vampire who can fly. It seems to be the case with the other actresses playing the Brides too. All three of them did their own stunts for the flying scenes.
- Kate Beckinsale likewise immediately signed on after seeing the script, despite the director worrying she wouldn't want to do it after having just done Underworld.
- Better on DVD: The film earned over $65 million in its first week of DVD sales - which is more than half of the theatre revenues.
- Creator Backlash: A minor example. Kate Beckinsale hated the corset she had to wear as Anna, saying she wanted to burn it all by the time filming was over.
- Deleted Scene: Aleera originally featured in the masquerade ball. Elena Anaya spent quite some time rehearsing the complicated dance routines - only for all her scenes to be cut. A photo exists of her in a sparkly red gown licking Anna's neck.
- Enforced Method Acting:
- Silvia Collocca is terrified of heights and therefore was not acting during the scene where Verona and Aleera are hanging upside down and getting yelled at by Dracula.
- Accidental example. While shooting Velkan's death scene, the rock underneath him was covered with spiders and they bit him quite ferociously.
- Fake Brit: Australian Hugh Jackman uses a British accent for Van Helsing, as does New Zealander David Wenham for Carl.
- Fake Nationality: British Kate Beckinsale and Richard Roxburgh play Romanians. The Brides' nationalities are never stated, and it's possible Aleera and Verona could be Spanish and Italian respectively like their actresses. However Marishka has an ambiguously Eastern European name and accent, and played by American Josie Maran.
- Irony as She Is Cast: Silvia Collocca (Verona) is terrified of heights. And yet she plays a vampire who spends more time in the air than she does on the ground.
- No Stunt Double:
- Josie Maran, Silvia Colloca, and Elena Anaya did all of their own stunts for the flying scenes.
- Richard Roxburgh did his own wire work stunts.
- Playing Against Type: David Wenham, who was seen portraying the very stoic Faramir less than a year ago, plays Friar Carl, a very nervous and scared character who helps to provide the film with very hilarious moments. This is pretty much his only playing against type character in a long time. He returned to play no-nonsense characters in films like 300, Australia or The Proposition.
- Production Posse: Kevin J. O'Connor, who frequently collaborates with Stephen Sommers, appears here as Igor. The role was written for him. Alan Silvestri returned to compose the music after The Mummy Returns, Bob Ducsay edited the film as with previous Sommers movies and Adrian Biddle did the cinematography (his last collaboration before his death the following year).
- Real-Life Relative: In the Spanish dub, real life brothers Nuria and José Luis Mediavilla voiced both Anna and Velkan respectively. However, their father Pepe Mediavilla was the voice of Frankenstein's Monster.
- Romance on the Set: Silvia Colloca and Richard Roxburgh fell in love and got married the same year the movie came out - Hilarious in Hindsight when you realize Dracula actually married one of his brides (Verona)! What's more is that her actress claims that Verona is the Queen Bride - so First Girl Wins after all.
- Stillborn Franchise: There were plans for a sequel and a spinoff TV series, Transylvania, but they were scrapped in light of the lower-than-expected box office and mostly bad reviews.
- Trope Namer: Do Unto Others Before They Do Unto Us was named after Igor's line.
- What Could Have Been:
- The Creature from the Black Lagoon was originally going to be the one guarding the werewolf cure in Dracula's castle. This apparently would have prevented Igor's Disney Villain Death by ripping his face off when it entered the scene.
- Also, the storyboard from that scene refer to Anna as "Mina", implying she was originally meant to be Mina Harker.
- Michael Bay was attached to direct, but opted to make The Island instead.
- The Wiki Rule: The Van Helsing Wiki.
- Writing Around Trademarks: Inverted. The producers specifically changed Van Helsing's first name from Abraham to Gabriel so they could hold onto certain rights for the character. Also because Stephen Sommers didn't think he could have a lead with Abraham as a first name.
